What is a vertex?

by Mark Dawes (January 2020)

For many people, maths is precise.  Mathematics is often exact.  Mathematical vocabulary however isn’t.

Years ago I was asked by a colleague “is a vertex where three or more faces meet?”.  I agreed that it was.  The next question was “what is the thing at the top of a cone called?”.  (My initial flippant response was “it depends which way up it is”, whereas the best answer is probably, “ice cream and a flake”).  It is, of course a vertex too.  We also use ‘vertex’ in lots of other mathematical situations, for example in graph theory, with intersecting lines, in 2D shapes and at the turning point of a quadratic graph.

Cate Middleton, subject leader for mathematics at Littleport and East Cambs Academy is keen on mathsy art.  When I saw some of the things she has done with her pupils I was blown away by both the quality and the quantity of the ideas she had gathered from lots of different places.  With Cate’s permission, I share some of these here.

Boardgame Maths – Kingdomino

By David Banham (June 2019)

I am not sure whether my love of maths was inspired by my love of games and puzzles or vice-versa. What I do know, is that I am always fascinated by the intersection of these two great things in the Venn diagram of my life.

A recent example is the game Kingdomino by Blue Orange games. The game, which won the Spiel des Jahres in 2017, is beautiful in its elegance and simplicity but has an intriguing mathematical coincidence at the heart of its design.
